Longitudinal and radial development parameters of extensive air showers measured with charged particle and air Cherenkov light detectors of the Yakutsk array are considered. To estimate the average mass composition of the primary particles, the two-dimensional spread of shower parameters is an alyzed in comparison with cascade simulations using CORSIKA/QGSjet code. As a result, three fractions of the primary nuclei groups are estimated with the reconstruction error below 30% in the energy range Eo € (10 1T,1019 ) eV.
